Clean up windows accessibility backend

What was done:

 * Removed headers in src/gui/accessible/windows/apisupport: as of
   v13.1.0, MinGW supports most of the definitions in these headers.
   Including uiautomation.h should be enough.

 * Removed the QWindowsUiaWrapper class: it's not meant to be extended
   or itself instantiated, is an "ultra-thin" layer (it even preserves
   the "all-caps" Win types of function args), and is in effect only a
   MinGW-bound "kludge". Instead of this class, use the UI Automation
   API directly, with the assumption that it's available and fully
   functional, as specified in the MS docs. Any gaps between this
   assumption and what is delivered by MinGW are bridged with specific
   (and explicit) temporary "kludges".

 * Implemented said specific "kludges" in qwindowsuiautomation. For
   Windows builds, the header just includes uiautomation.h, and the
   .cpp is empty. For MinGW, the header contains definitions still
   missing from uiautomation.h, and the .cpp implements functions
   of the UI Automation core library through imports from the
   uiautomationcore DLL.

 * Windows plugins (and tst_qaccessibility): use the UI Automation API
   definitions directly, instead of the "ultra-thin" wrapper.

 * Windows plugin builds: use uiautomationcore library, if found.

What's intended:

 * Unburden Gui of the Windows UI Automation COM interfaces and other
   definitions that are copied in the uia*.h headers.

 * Make the Windows plugins independent of MinGW shortcomings.

 * Remove the QWindowsUiaWrapper class that essentially only hides these
   shortcomings and the "kludge" code needed to overcome them.

 * As MinGW adds further support to the UI Automation API over time,
   make it noticeable which workarounds are no longer needed. The
   current approach of hiding "kludges" in a wrapper class will also
   hide the fact that they're no longer needed, if/when that time comes.
